This report was the first report in the district series, and has a different format to later reports. It includes all natural hazards, not only earthquake hazards. It describes earthquake, flooding, meteorological, landslide and coastal hazards within Hurunui district and gives details of historic events. It includes district-scale (1:250,000) active fault and flood hazard maps. The report describes an earthquake scenario for a magnitude 6.9 earthquake near Cheviot, as well as flooding, meteorological, landslide, coastal erosion, storm surge, and tsunami scenarios. See Object Overview for background and usage information.

Sadly the Chapel has been badly damaged in the magnitude 6.3 earthquake that hit Christchurch 22 February 2011. See below. The Rose Historic Chapel formerly St Mary’s Convent Chapel is the sole survivor of a group of heritage buildings in Christchurch that once comprised the St Mary’s Convent complex for the Sisters of Mercy in North Colombo St...

After the magnitude 7.1 earthquake struck Canterbury on 4 September 2010, most media reports claimed that no lives had been lost. But In fact, this first earthquake killed at least 3000 chickens, eight cows, one dog, a lemur and 150 aquarium fish. University of Canterbury associate professor Annie Potts, along with co-author Donelle Gadenne, wrote Animals in Emergencies: Learning from the Christchurch Earthquakes, revealing what happened to the animals during and after the series of quakes. Annie Potts will give a public lecture, 'Animals and natural disasters: Learning from recent earthquakes', on Thursday 16 March, 7pm at UC Ilam campus, Christchurch.

Rugby World Cup 2011 (RWC 2011) Tournament partners have reluctantly announced that Christchurch will be unable to host the seven matches currently scheduled to be played at the AMI/Lancater Park Stadium in Christchurch. This follows a detailed assessing of damage to the Stadium, grounds and infrastructure caused by the 6.3 magnitude earthquake ...

Kia Kaha (in the little red love-heart on the fence) can be translated from the Maori language as “Be strong and fearless!” “Be Proud!” or “Stand tall!” The term is used in many situations to give encouragement and support to family, friends and mates. Taken one week after the 6.3 magnitude quake hit Christchurch 22 February 2011. Proce...

Active faults capable of generating highly damaging earthquakes may not cause surface rupture (i.e., blind faults) or cause surface ruptures that evade detection due to subsequent burial or erosion by surface processes. Fault populations and earthquake frequency-­‐magnitude distributions adhere to power laws, implying that faults too small to cause surface rupture but large enough to cause localized strong ground shaking densely populate continental crust. The rupture of blind, previously undetected faults beneath Christchurch, New Zealand in a suite of earthquakes in 2010 and 2011, including the fatal 22 February 2011 moment magnitude (Mw) 6.2 Christchurch earthquake and other large aftershocks, caused a variety of environmental impacts, including major rockfall, severe liquefaction, and differential surface uplift and subsidence. All of these effects occurred where geologic evidence for penultimate effects of the same nature existed. To what extent could the geologic record have been used to infer the presence of proximal, blind and / or unidentified faults near Christchurch? In this instance, we argue that phenomena induced by high intensity shaking, such as rock fragmentation and rockfall, revealed the presence of proximal active faults in the Christchurch area prior to the recent earthquake sequence. Development of robust earthquake shaking proxy datasets should become a higher scientific priority, particularly in populated regions.
